AEROPLANE.

Specification of Letters Patent.

Patented Sept. 13, 1921.

Application filed September 18, 1920. Serial No. 411,033.

To all whom it may concern Be it known that 1, MARK GoLniN, citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Aeroplanes, of which the following is a specification.

This invention relates to improvements in aeroplanes, and one of the principal objects of the invention is to provide the upper planewith means which may be inflated with hot air or with gas for the purpose of assisting in supporting the plane in the air, said means to be lined with asbestos or other heat insulating material.

Another object is to provide the lower plane with fuel containers for effecting inflation of the aforesaid device.

Another object is to provide the plane with a plurality of propellers for overcoming the air resistance in various directions.

Another object is to provide the aeroplane with auxiliary lanes which may be folded to form a parac ute in case of need.

Other objects will appear from the following description and claims.

All of these objects are attained by the means shown in the accompanying drawing comprising one sheet, in which Figure 1 is a side elevational view of my improved aeroplane in condition for flight shown in full lines, the dotted line position showing the auxiliary planes moved to the position for forming a parachute.

Fig. 2 is a fragmentary sectional view of one of the inter-wing struts.

Fig. 3 is an elevational view of a meansfor moving the rear auxiliary planes.

Like characters of reference refer to like parts in all views.

Referring more particularly to the drawing, 1 represents the fusilage of an ordinary aeroplane, and 2 represents the landing gear thereof. A suitable propelling means, engine and instrument board are provided, and may be of any suitable nature.

he wing structure differs radically from that at present used in that the wings or planes are each made hollow and provided with means for storing certain desired materials as will now be described.

The lower plane is shown at 3 and is provided with tanks which contain oil, gasolene or other liquid fuel or may contain the material for the production of a gas for insired one side may be of collapsible ma,-

terial similar to a balloon so that when desired the same may be inflated to assist in maintaining the plane in the air.

Both planes are properly stream-lined and are formed so that normally they offer but slightly more head resistance than the ordinary plane.

The inter-wing structure comprises two columns 5 which are also stream-lined and lined with asbestos or the like and which have located within them either lamps or burners 6 for the fuel carried by the lower plane, or apparatus for producing hydrogen or other gas for inflation of the upper plane. At the rear of the'planes 3 and 4, the members 5 taper down forming two oblique sides 7, for a purpose which will presently appear.

Mounted at the front of planes 3 and 4 are a pair of hingedly mounted members 8, the upper one of which acts as the substitute for the ailerons and may be warped by any suitable mechanism controllable from the instrument board. Both members 8 are however movable to the position shown in dotted lines in Fig. 1 in which they form the mouth of a funnel shaped device of which the planes 3 and 4 are also part.

Hingedly mounted to the rear edges of the planes 3 and 4 are a pair of plane members 9 which normally form rearward extensions of the planes 3 and 4 and assist in supporting the structure. These members 9 are cut away near their middle portions so as to fit about the fusilage when folded inward. Any suitable connections may be made from these members 9 to a suitable hand control located at the instrument board whereby the members 9 may be folded to the position shown in dotted lines in Fig. 1 in which they lie snugly against the edges 7 of the inter-wing struts as above described.

In Fig. 3 is shown one means of operating the rear auxiliary planes 9. In this figure. 12 represents a hand wheel which is located near the operators seat and is provided with a suitable handle 13. This hand wheel will turn a stub shaft 14 which has a bevel gear 15 fast on it. Gear 15 meshes a gear 16 on a vertical shaft 17 carrying at its upper end a gear 18 which in turn meshes a gear 19 on till the front end of a horizontal shaft 20 which carries at its rear end a bevel gear 21 meshing a gear 22 on a vertical shaft 23. The lower end of shaft 23 carries a gear 24 which meshes a gear 25 on a shaft 26 by which means motion is transmitted to a similar shaft 23 on the opposite side of the aeroplane. Each shaft 23 1s provided with upper and lower worms 27 and 28 on which are respective blocks 29 and 30 connected respectively by links 31 and 32 to the upper and lower rear auxiliary wing members 9. It is obvious that by operation 'of handle 13 the wing portions 9 may be folded in against the fusilage as shown by dotted lines in Fig. l.

Radiating from the four corners of the aeroplane are four auxlhary propellers 10 which are provided with individual controls of any suitable nature for connecting them with the driving shaft of the engine.

In use, the general purpose of the invention is to provide an aeroplane which may be speedily transported from place to place and when it has been moved to the desired location may be inflated and anchored in a manner similar to a balloon so as to form a fortification. Should the device for any reason start to fall through having the gas container punctured or fromother causes, the operator closes the rear auxiliary planes and opens the front auxiliary planes with the result that a parachute form is attained which will insure a safe landing.

If the hand control of the rear planes be deemed too difficult, aclutch may be provided for throwing the wing moving mechanism into gear with the main shaft of the engine.

If desired the plane may be equipped with the various devices shown in my allowed application Serial No. 289,566, filed 'April. 12th, 1919, and my Patent 1,321,733.

When the device is used as an anchored balloon, the air currents will tend to blow the device about, and to offset the effects of these currents the auxiliary propellers 10 are provided. According to the drection in which the wind is blowing, the proper propeller or propellers will be set in motion.

While I have described what I deem to be the most desirable embodiment of my invention, it is obvious that many of the details may be varied without in any way departing from the spirit of my invention; and I therefore do not limit myself to the exact details of construction herein set forth nor to anything less than the whole of my invention limited only by the appended claims.

Whatl claim as new and desire to secure by Letters Patent is 1. In a device of the class described, the combination of a fuel-containing wing structure, a wmg structure adapted to be inflated, and an 1nter-wlng structure connectmg the two and comprising means for utilizing fuel from the first said structure for inflating the second said structure.

2. An aeroplane having a lower plane, fuel containers in said lower plane, an upper plane adapted to be inflated, inter-wing structure, and burners in said inter-wing structure for burning the fuel from said containers for effecting inflation of said upper plane, said upper plane and interwing structure being lined with non-heatconducting material.

3. An aeroplane having a fixed wing structure, movable wing structure secured to the front of said fixed structure and adapted to be moved relatively thereto, movable wing structure movably secured to the rear of said fixed structure and adapted to be moved to position for forming a parachute-like structure, inter-wing structure adapted to cooperate with said movable wing structure for forming said parachute-like structure, and means for moving said movable wing structure to form said parachutelike structure.

In testimony whereof I have affixed my signature.

MARK GOLEIN.
